Circuit Description Application: The TX-3312N transmitter is a periodic type transmitter used to remotely control a duck decoy. There are two function buttons; one button activates functions set in the decoy receiver and the second button stops the functions. Circuit: The circuit is a simple encoder IC that creates a unique identification code and modulates a simple Colpitts oscillator circuit. The antenna is a loop etched on the PWB. Antenna tuning is accomplished with a trim capacitor in the transmit loop. Receiver: The companion receiver is a simple super-regenerative design. Several control functions are set in the decoy circuit whereby a motor control circuit accomplishes movements of the decoy. The decoy has been approved under a Declaration of Conformity per Part 15, Subpart B.

Dear Mr. Curtis, I have checked into the matters you raise and have answered below. Thank you for your kind comments. Regards, Tom > -----Original Message----- > From: Certification Manager [SMTP:[email protected]] > Sent: Friday, July 28, 2000 1:13 PM > To: Tom Tidwell > Subject: FCC Application TX3312N > > Dear Mr. Tidwell, > > Thank you very much for your business. Your application was truly well > organized and a pleasure to review. > > I have the following issues to resolved before I can grant your > application. > > 1. The test report says that antenna 2017 was used and the equipment > sheet shows that antenna as calibrated on 01/25/99. Since the test was > performed on 6/6/00, that antenna is beyond an annual calibration. > Please explain how this complies with ANSI C63.4 clause 4.4.1. It is > possible to go more than 1 year between "official" calibrations if you > have some other means of checking that your antenna factors are ok in > the interim. Let me know what it is that you do. [Tom Tidwell] Apparently the automated test equipment list generation picked up a calibration date from a list that was not updated. Probably it did not update the file link. The last calibration on that antenna was 2/26/00. Our records show that the antenna was checked on 1/26/99 and a calibration extension was issued for one week based on the calibration check. The antenna was then calibrated 2/26/00. > 2. Similarly, your equipment sheet does not appear to contain any > cables longer than 2m and does not contain cable C1A noted in the data > sheet. Is this cable a calibrated item? How long is it? [Tom Tidwell] The cable is the feeder cable that is buried in conduit and connects from our control building to the OATS. The cable is 30 m in length. It is calibrated annually. The last calibration was 2/26/00. > 3. I am unable to verify the code O4T in the FCC database. I think > this means that when I try to fill out the 731 form on the TCB upload > site that I will not be able to proceed.

I tried both > O4T and 04T. [Tom Tidwell] I paid the fee on-line via credit card on 7/12/00 10:24 AM. I have a remittance ID number (64729) and an authorization number (012890). I will FAX you the confirmation and transaction notice forms that I printed from the FCC site. I will FAX these to you. > 4. The schematic says 433MHz. Please confirm that you want a grant for > just 434 MHz. 433MHz actually makes a lot more sense if you consider > the restricted band at 1300MHz. You comply either way. This is not > something that will hold up your grant, it's just for your information. [Tom Tidwell] Actually the transmitter is nominally 433 MHz by design. I agree that that makes more sense. Yes, 433 MHz - 434 MHz would be preferrable. > 5. For your information I called up your accounting department and they > gave me a credit card number to bill against.
